Yeah, i think its mainly Coka Cola. But its just freshly thrown on, then she quickly sucks it up with the bissel.
I've also seen her make up a big mixture on the carpet with things like raw eggs, wiped cream, cola, orange juice etc etc but again this is just sucked up soon after she lays it on. And the carpets are polyprops.
Its all a con really. But i can see why a viewer (with no carpet cleaning knowledge) could be taken in by it all.
